Abstract
A defeat resistant ballast filtration system for a recreational boat includes a pump to pump water into a ballast tank. The system also includes a filter having an inlet in fluid communication with an outlet of the pump and an outlet of the filter is in fluid communication with an inlet port of the ballast tank. In addition, the system includes a pressure sensor that is configured to measure an upstream pressure at the inlet of the filter and to measure a downstream pressure at the outlet of the filter to determine a pressure differential. The system includes an electronic control unit (ECU) configured to determine when the pressure differential is not within a predetermined range, and in response to not being within the pre-determined range, the ECU is configured to make the pump inoperable to pump the water into the ballast tank.
